Participants

Procedure

Cyclohexyl isocyanate (0.70 mL, 5.50 mmol) and triethylamine (1.74 mL, 12.5 mmol) were added to a stirred suspension of 3-[2-(chloromethyl)-1H-imidazo[4,5-c][1,5]naphthyridin-1-yl]propan-1-amine hydrochloride (prepared as described in Parts A-E of Example 92, 1.56 g, 5.00 mmol) in dichloromethane (25 mL). A solution eventually formed from which a solid precipitated. The mixture was allowed to stand at room temperature overnight, then the solid was isolated by filtration and washed with a minimal amount of dichloromethane to afford 1.52 g of N-{3-[2-(chloromethyl)-1H-imidazo[4,5-c][1,5]naphthyridin-1-yl]propyl}-N-cyclohexylurea as a white solid.
